Cedarwood hangers help repel moths and other insects.
Mothballs used to be a popular way of keeping insects at bay, but they contain chemicals that may be harmful to our health. Good thing there’s something else inside our house that acts as a natural insect repellent: cedarwood hangers. The scent of the oil in cedarwood deters moths and stops them from chomping on our clothes. But it’s advised to sand the hangers or re-coat them with cedar oil every few months to maintain their pesticide properties.
smarter individual would use the other hook instead of a key....
Just screw it in by hand, it isn't that difficult.
#2 not sure it would work. cars have safety glasses which prevent shattering. you can buy special purpose hammers though.
WTF? Spell much?
